The precise measurement of the properties of the stars, in particular for the slightly-evolved star A, means a comparison with theoretical evolutionary models could be informative. We did this, using tabulations from the parsec models [1]}, via the mass–radius and mass–\(T_{\rm eff}\)  diagrams [2]}, [3]} (Fig. REF ). We did not consider any constraints on metallicity as there are no precise determinations available.
